IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 195,524, datedSeptember 25, 1877; application filed March 19, 1877.

To all whom it may concern:

Be it known that I, HENRY Gr. MORGAN, of Eau Claire, in the county ofEau Claire and State of Wisconsin, have invented new and usefulImprovements in Thin-Couplings; and I do hereby declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making a part of this specification, inwhich- Figure 1 is a perspective view of my improved coupling. Figs. 2and 3 are perspective views of the parts composing said couplingseparated from each other, and Figs. 4 and 5 are side views of the same.

Similar-letters of reference occurring on the several figures indicatelike parts.

My invention has for its object to furnish an improved thill-couplingcombining strength and efficiency with a simple and ready operation ofthe parts composing the same, whereby its accidental detachment isrendered impracticable, and at the same time the separation of partseasily accomplished, if desired; and it consists in the details ofconstruction and general arrangement of parts, all as will behereinafter more fully described, and pointed out in the claims.

Referring to the drawings, A represents the thill-iron, having anenlarged head, provided on one side with a cap, G, from which extends acylinder, 0, between which and the enlarged head is provided aneck-iron, D, leavinga recess at the bottom between the cylinder and thehead of the thill-iron, as shown in Fig. 3. F represents the connectingjaw, provided at one end with the hollow cylinder B, open at one end,and having a longitudinal slot, E, at its upper side, which is providedwith a projecting shoulder, H, at the outer end, as fully shown in Fig.2.

The parts thus constructed and arranged are connected together, as shownin Fig. 1, by inserting the cylinder Gin the hollow cylinder B, the neckof the thill-iron A passing through the slot E until the two parts arefitted closely together, when, by depressing the outer end of thethill-iron A, the cylinder 0 turns partially around in the hollowcylinder B, and the projection H enters the recess between the cylinder0 and the head of the thill-iron, thereby locking the parts in place andpreventing their accidental lateral displacement.

When it is desired to disconnect the parts, the thill-iron Ais raised atright angles to the coupling, thereby withdrawing the projection H fromthe recess, and permitting of the easy separation of the parts.

Having thus described my invention, I claim as new and useful- 1. In athill-coupling, the connecting-jaw F,

having hollow cylinder B, provided with slot E and projection H, incombination with the thill-iron A, having cylinder 0, cap G, andneck-iron D, the several parts being constructed, arranged, and combinedto operate substantially as and for the purpose set forth.

2. In a thill coupling, the thill-iron A, having cap G, provided withthe cylinder 0 and neck-iron D, constructed with a recess at one side,at the base of the cylinder, for engagement with the projection H of thehollow cylinder B, substantially as and for the purpose specified.

HENRY G. MORGAN.
